Very nice watch! I think genuine comes out in 2 version. One is open back , the other it is not. Which one do you have and from which seller did you buy it , if i may ask?
Hello Goodey
I bought it from a non TD www.perfectwatches.cn
No scam site but they quote sapphire crystal in nearly all models and i doubt it, and miyota quality but they are simple A21J movements
Anyway, it seems my model is not in the catalogue anymore
